), or the frame to which these are attached (
3) is attached to and detached from the main body of the tractor (1). Therefore, when the frame (3), lift arm (2), etc. are attached to the tractor (1), this control valve (5) By connecting the oil supply line etc. from the hydraulic pump on the tractor (1) side to the control valve (5), the valve (6) of the control valve (5) can be raised and lowered by operating the lift lever (7). The lift arm (2) of the front loader as described above can be freely operated to the lowered position, and if the operating mechanism joint aQ is connected to this control valve (5), the operating lever (9) can be moved from the cockpit (8). ), the control valve (5) of the front loader (4) can be freely operated by operating the control lever C9). If only part (9) is located in the cockpit (8) cabin and isolated, or if operating mechanism joint α0 is removed from control valve (5), this lift lever (7) can be operated directly from the front loader (4) mounting operation position, making it easy to attach and detach.Moreover, since the operating mechanism joint αQ can be attached and detached at this control valve (5), the front Although the loader (4) has the above-mentioned functions, it is easy to operate and has a simple structure, and the connection of the operating mechanism joint QO can also be simplified.

First, when connecting the operating mechanism joint aO to the control valve (5), insert the plate-shaped part (to) of the shaft (to) of the attachment/detachment lever (7) into the notch part of the fixing plate (E) and hole (C). By aligning the grooves 0 to 0 of the joint aO with this fixed plate (2) and moving the joint α0 laterally toward the frame (3), the recesses of both connection terminals @ (to) and both grooves @ 1) are aligned. (6) into the groove part @) and are connected to each other, and by rotating the attachment/detachment lever (7), the control valve (5) and the operating mechanism joint αQ are fixed. Conversely, connect the operating mechanism joint α0 to the control valve (5)
In case of separating from the joint aO, the attachment/detachment lever (to) may be returned to its original position and the joint aO may be laterally moved outward.
